LOUD NOISES due to Sunroof? on 2012 Cadillac CTS

I've have the gasket around the sunroof replaced, reseated, reseated once again and the glass panels moved around a bit, all in an effort to reduce the bloody noise in my 2012 CTS! I've been told by several people that this isn't normal. On the flip side, GM Rep's are now telling me that yes - this is normal! It's like driving down the highway in a glass bubble. Any ideas?
